This article is authored by AMD engineer Longley Zhang. In AMD SoC devices (AMD Zynq™ 7000 SoC, AMD Zynq UltraScale+™ MPSoC, AMD Versal™ Adaptive SoC), a common boot method is to load an image from external memory (QSPI Flash, eMMC, etc.) to boot directly into Linux. However, during board debugging, it is often necessary to … Read more
1. Compiling U-Boot First, let’s review how to compile U-Boot. (1) Set temporary environment variables export ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- (2) Specify board configuration and generate .config file make xxx_defconfig (3) Compile make -j8 (4) Clean build make distclean Next, we will analyze the top-level Makefile in the U-Boot root directory to explore what happens behind these … Read more
